Pokemon Black & White is scheduled to air in Fall 2010 in Japan so judging by the remaining time till show ends, I don't think Ash will win Sinnoh League to get a shot at Elite 4.

Sinnoh League arc start from July in Japan and Black & White is speculated to start in October(or possibly November) so they're probably not gonna have enough episode for Ash to win the league and challenge elite 4.

either way, i really want Ash to win the league and atleast challenge the Elite Four. and I want Ash to use Charizard effectively. like against Brandon's dusclops...that was a fail.but like in the 3rd movie, against entei, that was amazing!but charizard is freaking powerful now, by far Ash's most powerful pokemon. better than stupid infernape

It would have beaten Dusclops if ash hadn't been stupid. Plus there were some weird game anime mechanics there:

1) Will-o-wisp should not affect a fire-type pokemon. Let alone be on the same level as flamethrower2) Ash should have realized that Seismic Toss wouldn't of worked on a Ghost type3) Ash only used one set-up if I remember (which failed); he didn't use any strategy

But he has beaten Articuno, beat Gary's Blastoise, fought well against an Entei (Entei eventually used the Unown's power to have large spikes fly out to give it the advantage), had a very close match with Blaziken (which I feel Ash did not use Charizard effectively again)

Aside from all of this, who else would you consider to be Ash's "strongest Pokemon"?

oh I know. I have a feeling that that penguin of his is going to rock a few of Paul's pokemon. plus, since barry will be so enthusiastic, paul will get angry and maybe his emotions will mess with him again but paul is going to win for sure
